Display apparatus

Abstract

A display apparatus includes first and second display panels, a driver chip and a flexible printed circuit board. The driver chip disposed on the first display panel provides the first display panel with first and second driving signals. The flexible pcb electrically connects the first and second display panels to transfer the first and second driving signals to the second display panel. Each of the first and second display panels includes lower and upper substrates, a liquid crystal interposed between the lower and upper substrates, a combining member combining the lower and upper substrates and has an opening portion formed between sides of the lower and upper substrates, and a sealing member sealing the opening portion. By using a single chip to drive both LCD panels, both size reduction and yield/productivity increase are achieved.
